The control plate 20 has vertical purpose which will presently appear. To the slots 24 corresponding to the abutments 22, and

To the assembly plate 11 is secured a 55v 1'. "Ifhe pivot maybe 01 any 1construction suitfiat spring 26 carrying at its free end a stop 2'7 adapted to enter one of the slots 24 when the cam end 18 is engaged by the corresponding abutment 22. I

Over the spring 26, a horizontal ear 28 is struck out of the plate 11 and has a bell crank lever 29 pivoted thereto, one end of the lever engaging the upper extremity 30 of the spring 26 in a manner to push it toward the back 5 of the slide 4 when the other end of the lever is pushed into the slide, as illustrated in Figure 6. The last named end of the bell crank lever registers with a slot 31 in the back 5 of the slide 4 and is engaged by the sash plate 7 in the closed position of the sash. In this position, the bell crank lever compresses the spring 26 toward the plate 11 and holds the stop 27 out of the slot 24. When, however, the sash is swung on release of the latch 13, the sash plate 7 clears the free end of the bell crank lever 29, permitting this end to project through the slot 31 .as shown in Figure 7, whereupon the spring 26 throws the stop 27 into one of the slots 24 of the fixed control plate 20, so that the slide 4 cannot be moved farther than the length of a slot 24.

When the sash is tilted out of contact with the upper ends of the opposed slides 4, the latter are likely to lean away from the grooves 3 and towards the interior of the window opening. In order to overcome this tendency, the control plate 20 is formed at one of its vertical edges with a shoe or inbent flange 32. The assembly plate 11 carriesa hooked lug 33 adapted to engage behind this flange when the latch 13 is released q by contact with one of the abutments 22, as 35 ber 4 as shallow as possible in order not to reduce the width of the window opening any more than absolutely necessary. The usual sash cord must obviously be secured within the member 4, and the usual knot at the attached end of the cord would require corresponding depth in the channel4 or would interfere with parts of the plate 20. Accordingly, the invention provides means for securing the cord in a flat condition or without the usual knot.

At the upperend of the assembly plate 11 is formed a loop 34 through which the sash cord 35 is threaded. Below the loop, a downwardly extending hook 36 is struck out of the plate 11, and the cord 35 is carried beneath this hook.

' Between theloop 34and hook 36, a laterally exknot.

It will now be seen that the sash is in condition for tilting only when in certain vertical positions determined by the abutments 22.

Moreover, on tilting of the sash, a stop devicefor limiting the sliding of the sash comes into action. Also, in these positions, inward tilting of the slides disengaged. by the sash is prevented. The special anchorage of the sash cord makes possible a comparatively shallow channel slide 4 which takes up very little of the width of the Window opening.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention, as indicated by the appended claims.
